support native iOS simulators on Apple silicon mac

[kewlbear]

Thanks for this great project!

I've added support for building XCFramework containing iOS simulator for arm64 arch.

Please let me know if I missed something.

Have you tested this from cocoapods? I was having some issues when trying to set up an xcframework to work from it

I'm trying to get my nodejs-mobile builds working on M1 simulators as well, specifically the react-native package. Unfortunately it looks like this library isn't maintained here anymore and has moved to https://github.com/nodejs-mobile/nodejs-mobile.

I'm trying to reverse engineer the changes here with no luck so far. If possible, could you explain a bit about what changes you made @kewlbear? It would greatly help my understanding.

In tools/ios_framework_prepare.sh you can see that I've changed it from building for x86_64 simulator to all simulators except i386, that is x86_64 and arm64 simulators. That is the key part of my changes, the rest is just making it possible.
